What Is the CDA? How Is It Measured? How Does

Question

Examlex · Accepted Answer

The Answer is The CDA, or contralateral delay activity, is a neural response that occurs in the brain when individuals are required to hold information in working memory. It is measured using electroencephalography (EEG), which records the electrical activity of the brain. Specifically, the CDA is measured by analyzing the amplitude and frequency of neural oscillations in the brain, particularly in the parietal cortex.

The CDA is known to change with memory load, meaning that as the amount of information held in working memory increases, the amplitude and frequency of the CDA also increase. This suggests that the CDA is directly related to the cognitive effort required to maintain and manipulate information in working memory. As memory load increases, the brain's resources are more heavily engaged, leading to a larger CDA response.

Overall, the CDA provides valuable insights into the neural mechanisms underlying working memory and how the brain handles cognitive tasks related to memory retention and manipulation. Its measurement and analysis can help researchers and clinicians better understand cognitive processes and potentially develop interventions for individuals with memory-related difficulties.
